This suggested age makes the Moon a lot older than some recent estimates, which claim our lunar neighbor is 4.3 or 4.4 billion years old.
If the results are accurate, it means the giant impact that created the Moon must have occurred fairly early on in the Solar System’s history.

That’s why Barboni measured another important set of elements: lutetium and hafnium.
As the Moon took shape, its materials separated into an inner mantle surrounded by a crust, and that process would have changed the ratio of lutetium and hafnium within various regions of the Moon.
Scientists say they have figured out the most precise age for the Moon than ever before, thanks to samples of lunar rocks gathered during NASA’s Apollo 14 mission.
Our planet would have been completely wiped out by the giant impact, so life could not have started forming on Earth until after the planet became whole again in the wake of the collision.Zircon is thought to have crystalized back when the Moon was still volcanically active; magma from the lunar interior erupted onto the surface, where it eventually cooled and crystalized into the zircon.“This mineral is just the king when you try to understand any processes, because it is amazingly sturdy,” says Barboni, an assistant researcher in department of earth, planetary, and space sciences at the University of California Los Angeles.It’s a conversion that happens at a specific rate, so scientists can use the ratio of these elements within zircon to figure out how old the rock is.But dating when the rock formed doesn’t give you the entire picture, since the Moon is much older than when the zircon crystalized on the lunar surface.
